我使用 node.js、express 和 socket.io 进行了聊天。这是 app.js 代码：

var express = require('express'),
    app = express(),
    server = require('http').createServer(app),
    io = require('socket.io').listen(server);

server.listen(process.env.PORT || 8080);



app.use(express.static(__dirname + '/'));


io.on('connection', function(socket)
  socket.on('message sent', function(data)
    io.emit('receive',  msg: data.msg, uname: data.uname, uid: data.uid, uimg: data.uimg );
  );

  socket.on('message sent room', function(data)
    console.log(data.mid);
    io.in(data.uroom).emit('receive',  msg: data.msg, uname: data.uname, uid: data.uid, uimg: data.uimg, mid: data.mid );
  );

  socket.on('join', function(data)
    io.emit('join user',  uname: data.uname, uid: data.uid );
  );

  socket.on('create', function (room) 
    socket.join(room);
  );

);

这是我的haml文件中的代码

  %script:src => "https://cdn.socket.io/socket.io-1.2.0.js"

    - if Rails.env.production?
      :javascript
        var socket = io.connect('https://myherokuappurl.herokuapp.com/');
    - else
      :javascript
        var socket = io.connect('http://localhost:8080/');

    :javascript
      var userId = "#current_user.id";
      var userName = "#current_user.name";
      var userImg = "#@userImage";
      var room  = "#@conversation.id";
      var messageId = 0;

      $(document).ready(function()
        socket.emit('create', room);
        $( "#m" ).focus();
        var wtf    = $('.panel-chat');
        var height = wtf[0].scrollHeight;
        wtf.scrollTop(height);
      );

      $('form').submit(function()
        var message = $('#m').val();
        $.ajax(
          type: "POST",
          url: "#dashboard_messages_path",
          dataType : 'json',
          data: 'message' : 'conversation_id': room,
                 'body': message,
                 'user_id': userId ,
          success: function(data) 
            console.log(data.id);
            messageId = data.id;
            socket.emit('message sent room', msg: $('#m').val(), uname: userName, uid: userId, uimg: userImg, uroom: room, mid: messageId);
            $('#m').val('');
          
        );
        return false;
      );

      socket.on('receive', function(data)
        var message = '<tr><td class="td-chat"><div class="text-center"><img  class="avatar center-block" src="'+data.uimg+'"  ></div></td><td><small><strong>'+data.uname+':<br></strong></small>'+data.msg+'</td></tr>';
        var currentMessageId = data.mid;

        if (data.uid != userId) 
          $.ajax(
              type: "GET",
              url: "#dashboard_message_read_path",
            dataType : 'json',
              data: 'message_id':currentMessageId 
            );
        
        $("#table-chat").append(message);
        var wtf    = $('.panel-chat');
        var height = wtf[0].scrollHeight;
        wtf.scrollTop(height);
      );

      socket.on('join user', function(data)
        if (data.uid != userId) 
           $("#userjoin").text(data.uname + " se ha unido!").show().fadeOut(5000);
        
      );

但为了完成这项工作，我必须刷新聊天页面。我注意到用户第一次进入聊天页面时，它没有以下文件：
